The standalone tag reader circuit (STARC) is an integrated

circuit dedicated to the automotive immobilizer applications.

It combines the antenna drivers and demodulator necessary to

interface with a transponder.

A low dropout voltage regulator and a physical interface fully

compatible with the ISO 9141 norm are also available.

The STARC is fabricated with the SMARTMOSTM3.5

technology. This process is a double layer metal 1.4μm

45V technology, combining CMOS and bipolar devices.

? Contactless 125 kHz tag reader module:

– Self synchronous sample and hold demodulator

– Fast read after write demodulator settling time

– Low resistance and high current antenna drivers, 2W @

150mA (typ.)

– Bidirectionnal data transmission

– Multi-tag, multi-scheme operation

? Low dropout voltage regulator:

– Wide input supply voltage range from 5.5V up to 40V

– Output current capability up to 150mA DC with an

external power transistor

– 5V output voltage with a ±5 accuracy
